“…Multiple studies have shown a positive linear correlation between surface roughness and adhesive strength. 8,9,25,26 An increase of adhesion from 127 to 307 kPa at −10 °C was observed for R a rise from 0.5 to 2.55 μm. 5 In a previous study of Chu, the adhesive strength increased from 270 to 370 kPa, while R a ranged from 0.81 to 2.03 μm.…”

Ice adhesion is important when designing aircraft anti-icing/de-icing systems. Major and minor grooves are common in the skin of aircraft. However, the effects of millimeter-scale grooves on ice adhesive strength have not been given due attention. Specimens with varying depths, widths, and numbers of grooves were fabricated by machining to investigate the ice adhesive characteristics of large-sized grooved aluminum surfaces. After the ice cube was frozen on the surface using a silicon mold, the adhesive force was measured using a self-assembled shear adhesive force setup. A correlation between groove size and apparent adhesive strength in the perpendicular loading direction was established based on the experimental results. Every 1% increase in the groove width ratio was associated with an 18.7 kPa increase in apparent adhesive strength. The increasing speed of the adhesion rapidly decayed as the groove depth increased. The increase in adhesion reached 99% of the maximum increase when the groove depth reached 0.8 times the width. The number of grooves had little effect on the adhesion when the total width of the grooves was kept constant. Stress distribution analysis was conducted using the finite element method, and the results were in accordance with the cracking phenomena in the experiments. The adhesive strength in the parallel loading direction was 30% lower than that in the perpendicular loading direction for all six chosen surfaces. This study is the first to propose a quantitative relationship between the surface textures of millimeter-sized grooves and ice adhesive strength. The loading orientation also had a substantial influence on adhesion. The results will serve as a valuable reference for future studies on ice adhesion on textured surfaces and for improving the performance of anti-icing/de-icing systems.

“…The properties of ice are affected by flying and meteorological parameters such as airspeed, temperature, and liquid water content. Many studies have tracked the effects of these parameters on ice adhesion. − For surface properties, existing quantitative studies focus on hydrophobicity and surface textures.…”

“…The low solid/liquid interfacial contact area of the frozen droplet on the functionalized surfaces results in an adhesion strength of 0.109 kPa compared with the adhesion strength of ice crystallized on the bare stainless steel mesh substrate and solid stainless steel substrate (698 kPa at À10 C). [82][83][84] Average shear force experienced by the droplet for 7 mg cm À2 ZnO/TEOS/F-POSS on 177 μm pore mesh is 2.91 μN, whereas for 14 mg cm À2 ZnO/TEOS/F-POSS on 44 μm pore mesh the force is 2.85 μN. This difference in force is primarily due to the contact angle differences between functionalized meshes, which project a lower solid angle for lower loading and higher mesh pore size.…”

Mitigating ice adhesion on offshore and port structures is crucial for ensuring their safety and operational efficiency in cold climates. Ice adhesion, the molecular attraction between ice and a surface, can lead to increased structural loads, reduced stability, and restricted functionality. This work provides an overview of the different concepts, including the nature of ice adhesion, its consequences on structures, and effective strategies to minimize it. The strategies include surface coatings, surface roughness modifications, heating systems, de-icing and anti-icing systems, structural design considerations, and regular maintenance. These approaches aim to reduce ice adhesion, facilitate ice shedding, and enhance the resilience of offshore and port structures. By implementing these strategies, the integrity and performance of these critical infrastructures can be maintained, ensuring safe operations and supporting transportation and energy production in cold regions.
